QuestionCheck if the point (1,2)(1,2) is on the line defined by the equation y=3x2y=3x-2.

Studdy Solution

STEP 1

Assumptions1. The given point is (1,)(1,). The equation of the line is y=3xy=3x-

STEP 2

To verify if a point lies on a line, we substitute the x and y coordinates of the point into the equation of the line. If the equation is satisfied, then the point lies on the line.
So, we substitute x=1x=1 and y=2y=2 into the equation y=x2y=x-2.

STEP 3

Substitute x=1x=1 into the equation y=3x2y=3x-2.
y=3(1)2y =3(1) -2

STEP 4

Calculate the value of yy.
y=32=1y =3 -2 =1

STEP 5

Now, compare this calculated yy value with the yy coordinate of the given point. If they are equal, then the point lies on the line.
The yy coordinate of the given point is 22, but the calculated yy value is 11. Since these two values are not equal, the point (1,2)(1,2) does not lie on the line y=3x2y=3x-2.
